SPECIFICATION forming part of Letters Patent No. 691,136, dated January 14, 1902.

Application filed June 8, 1900.

T @ZZ whom it may con/cern:

Be it known that I, HARRY I-IARDWICK, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Devices for Correcting-Improper Registry of Party Colored Warp- Threads in Textile Machinery, of which the following is a specilication.

My invention consists of certain improvements in or modifications of the devices for correcting improper registry of party-colored warp-threads in textile machinery set forth in my application for patent, Serial No. 14,285, of 1900, filed April 25, 1900, the objects of my improvements being to so construct the mechanism that the tightening or slackening of the threads can be controlled more readily than before and to provide means for intentionally deranging the threads, so as to produce lines or stripes of color across the same, and thus permit departures from a true poi sition to be more readily noted.

The improvements have been devised with especial reference to the application of the invention to a warp-beaming machine, and in the accompanying drawings Figure 1 is a longitudinal section of the mechanism. Fig. 2 is an enlarged View of an escapement device forming part of the same. Figs. 3 and 4 are diagrams illustrating the purpose of one of the features of the invention, and Fig. 5 is an enlarged front or face view of part of the machine.

In a suitable framework 1 is mounted the shaft or spindle of the Warp-beam 2, said frame also carrying bearings for a number of guide-rolls 3, 4, 5, 6, 7, 8, 9, and 25 and being provided with guides for two sets of deilector-bars l0 and 11, each set having one bar for each thread of the warp, the bars 10 being disposed between the rollers 6 and 7 and the bars 11 occupying a position between the rollers 8 and 9 and each of said bars having an antifriction-roller 12, around which passes the thread which it is to control.

The threads are drawn from spools on a spool-frame 13, suitably located in respect to the frame 1, and said threads pass first to a suitable tension device, such as the roller 9, and a roller 14, which presses upon the roller 9 with such force as to impart the proper tension to the lthreads passing between the two Serial No. 19,539. (No model.)

rollers. Set-screws acting upon the bearings of either roller maybe used to cause this pressureof the rollers against one another.

From the rollers 9 and 14 the threads pass to and around the antifriction-rollers 12 of 8, thence to and around the roller 7, thence to and around the antifriction-rollers 12 of the bars 10, thence to and around the rollers 6 and 25, thence to and around the roller 5, thence down to and around the roller 4, thence to and around deflecting bars or rollers 15, thence to and around the roller 3, and finally to the beam.

The arrangement of the bars l0 in respect to the pair of rollers 6 7 and of the bars 11 in respect to the pair of rollers 8 9 is similar to that set forth in my former application, said barshaving movement between the rollers in a plane at right angles to the axes of said rollers; but in the present instance the roller 12 of each bar 10 is near the lower end of the same, while the roller 12 of each bar 1l is near the upper end of the same, and each bar opcrates by a downward movement, whereby the bars l0 serve to take up slack in or tighten the threads upon which they act, while the bars 11 serve to let out or slacken the threads subjected to their action. This action differs from that of the device of the former application in that in the latter tightening of either thread was effected by movement of its deiiector-bar in one direction and slackening of the thread by movement of its deflector-bar in the opposite direction, the use of two independent sets of bars in the present machine, one set intended for tightening the threads and the other set intended for slackening the same, being due to the fac-t that l capement mechanism connected to a keyboard, so that the operative movement of each bar is in but one direction. Each of the bars has teeth for engagement with the beveled tappet 16 and straight tappet 17 ot' an .anchorlever 18, which has an arm 19, connected by a cord, wire, or other suitable connection 20 to one ot the key-levers 21 of a keyboard located at the front of the machine, suitable guide rollers or pulleys 22 being provided for the proper direction of the connections 20, when the latter are in the form oit flexible the bars 1l, thence to and around the roller desire to control said bars by means of es- A l IOO cords or wires. When, therefore, either key is depressed, the escapement-lever of its corresponding defiecting-bar will be moved, so as to carry the straightl tappet 17 out of engagement with the tooth which is supported and bring the beveled tappet 16 into engagement with a higher tooth, the descent of the bar immediately forcing this upper tappet outward again owing to its beveled face, and thereby moving the lower tappet 16 into position to engage with the tooth above that with which` it was formerly in engagement. The escapement device is thus self-locking in the retaining position. Pressure of a tooth upon the tappet 16 tends to move said tappet farther into engagement with the tooth, and this tendency may be restricted by a suitable stop for instance, by a bar 26-with which the arm 19 of the escapement-lever comes into contact. Each depression of a key therefore 'Will permit of the lowering ot' its corresponding deilecting-bar to the extent ot' one tooth, the downward movement of the bars 10 being due to their weight, which may, if desired, be assisted in any suitable way, and the downward movement of the bars 11 being due to their Weight, in addition to the tension upon the warp-threads. rotated at any desired rate of speed, the entire series of threads, disposed closely side by side, pass from the upper roller 5 to the lower roller 4 in front of the attendant seated at the machine, who notes any tendency of either thread to move out of registry with its adjoining threads and corrects this tendency by proper movement of the bar 10 or 11 controlling said thread, movement of the bar 10 tightening the thread in case it has a tendency to creep ahead of its fellows and movement of the bar 11 slackening the thread, it' it has a tendency to lag behind.

In order that the departure of adjoining threads from their proper registry may be more readily detected by the attendant, I prefer to so derangethethreads as to forni straight lines of color, each extending across or part way across the series, one or more of these straight linesy being formed for each repetition of the pattern, so that as the linestravel from .the upper roller 5 to the lower roller 4 the attendant has ample time to note and correct any defective registry of the threads. The derangement ot' the threads may be such as to form a single line extending entirely across the series of threads or there may be a number of shorter lines disposed in dierent planes. The derangenient of the threads I effect by defiecting certain of the threads, or in some cases perhaps all ofthe threads, to a greater or less extent from a straight line before they reach the beam 2. Thus in Fig. 3 I have shown twelve threads a b c d cfg ht' j 7c Z, having spots outlining a rectangular figure. Certain of these threads are deliected, so as to bring spots of the threads ot b c d c h j 7c Z into line with spots ot' the threads fg, the extent of such deflection gradually The Warp-beam 2 being decreasing from d to @and from Z to h, or, as will be evident, the reverse method may be adopted, and spots of the threads b c CZ cfg h j Zt' may be brought into line with the spots on the threads a '12, the extent of deflection gradually decreasing from b to fand from 7c to g. This derangetnent of the threads, however, occurs wholly above the roller 4, the disposition of colors on the threads below the rol-1er 3 being such as to form the desired pattern. Hence the threads all bear the proper relation toeach other as they are wound upon the beam.

In front of the threads as they pass from the 'roller 5 to the roller4 I prefer to arrange an index-bar 23, marked or numbered to accord with each of the threads, so that the identity of any thread which is out of registry may be instantly determined and the corresponding marked, numbered, or positioned keymanipulated in order to correct Stich improper registry.

It will be evident that the sets of bars 10 and 11 maybe multiplied t'o any desired eX- tent in order to avoid crowding or to provide a greater range of control of each thread, and, if desired, the bars may all be constructed, as at 10, to tighten the threads or, as at 11, to slacken the same, the use of reversely-acting bars, however, being always preferred.

While the use of the keyboard is preferred because of its convenience, the escapementlevers may, if desired, be operated by other means-for instance, by direct manipulation of the connections 20, and the threads may take any desired course in their approach to the roller 4.

As in the machine of the former application the deflecting-bars 10 and 11 may be regarded as devices for regulating the tension upon the threads in their passage from the rollers 9 and 14 to the beam 2, movement of a bar 10 increasing the tension upon its thread and movement of a bar 11 decreasing the tension upon its thread.

Having thus describedy my invention, I claim and desire to secure by Letters Patentv 1. The combination in means for correcting improper registry of party-colored warpthreads in textile machinery, of two sets of guides for delecting the warp-threads from a straight course,one setof guides beingadapted to tighten the threads and the other set to slacken the same, and each set of guides having movable elements, one for each of the threads to be controlled, and provision for varying the detlective position of said warpcontrolling element of each set of guides, substantially as specified.

2.
